Grilled octopus is a delicious and popular dish in many Mediterranean cuisines. To make this dish, you will need the following ingredients: fresh octopus, olive oil, lemon juice, garlic, salt, and pepper. Start by cleaning the octopus thoroughly, removing the beak and eyes. Then, marinate it in a mixture of olive oil, lemon juice, minced garlic, salt, and pepper for at least 30 minutes. Preheat your grill to medium-high heat and grill the octopus for about 4-5 minutes per side, until it is charred and tender. Serve it with a squeeze of lemon juice and enjoy the tender and flavorful grilled octopus.
